question, what's the differences between the 84-86 Mustang 8.8s and the Explorer's beside the splines? I mean, are they the same lengths? Can the 31 spline shafts and posi from a Explorer fit into a Mustang 8.8? Both are disc brake and 5x4.5 pattern...hmmm.
This would be going into a YJ if that matters.

I believe the mustang and ranger 8.8's are too narrow.

Only '94+ Mustangs are 5 on 4.5. Earlier ones were 4 lug. I think they are narrower than explorers, but I don't know by how much. You can get 31 spline axles for them though.

Be carefull that the rear from a car of those years (84-86) really IS an 8.8.
Almost all of the cars in those years used the MUCH weaker 7.5 axle. :(
The 8.8 was only used begining in 86 on the V8 cars.
I currently have an 8.8 from a lincoln in my mustang, the wms is 61 ish and it has the 5 on 4.5 bolt pattern.

Why waste your time looking at mustang 8.8's? all explorers are the same, 31 splines drum or disc and some have posi's. Mustang and ranger 8.8's are narrower than explorer 8.8's and come with 27 splines, uless your 'lucky' and find the rare 29 spline ranger one........

Go Explorer and remove confusion!

Here's a link to some good ford axle info.... Look in history, there's information about 'car' axles.

ok, I guess I should have given a bit more info. Thanks to all who did give help.
I have a Explorer 8.8 in my YJ. I'm tring to help out a younger cousin built up his, and as cheaply as possible. I found a 8.8 from an 1985 Ford Mustang SVO that I know is 5x4.5 and has disc brakes. It's fairly local and is cheap, like $50. Hell, I paid like $500 for mine 5 years ago. I have spare 31 spline shafts, 4:10 gears, and a trac-loc posi. I'm wondering if my Explorers stuff would fit into the Mustang's 8.8 housing and tubes once the 28 spline one fail. Anyone know?
thanks again,

No the Explorer stuff won't fit in the Mustang Housing.... The Explorere shafts are longer because its a wider (WMS) axle than the 8.8 that came in the mustang. I think the carriers and gears might interhcange but i know the shafts don't....

damm, ok; thanks YYYJ.
Happen to know the length difference between the two? Is it a lot?
I might run a front D44 from a Scout, which would be a little narrower that the D30...hmm.

another overlooked candidate is the Thunderbird 8.8 axle. It is a bit wider than the Mustang, but is also only 4 lug (can be converted). Look for the V8 models as well as the TC (Turbo coupes). Turbo coupe axles were rear disc also.

damm, ok; thanks YYYJ.

Don't listen to these retards. :shaking:

According to the Neapco axleshaft catalog the Explorer
shafts are 27.625" (R) and 30.5" (L) for a total of 58.125"
plus the center pin (7/8") for a total of 59"

The Mustang shafts are equal length I think the pin is 3/4"

79-93 5-bolt (svo) were 29.125" for a total with the pin of 59"
79-93 4-bolt were 29" for a total with pin of 58.75" (wow 1/4" shorter)
94-95 5-bolt were 29 15/16" for a total with pin of 60.625" which
is actually wider than the Exploder axle

So if you throw some Neapco 31 spline axles (pn. NEV80) into it
you'd have a 59" 31 spline with disks 5 on 4.5".

My only concern is the bearings, the Explorer used f150 (pn. 6408)
bearings while the Mustang used Dana 35 (pn. 5707) bearings.
I don't have the bearing sizes handy though.

later.

All SVOs had the 7.5, not the 8.8. Check the cover. The 8.8 has a squarish cover with four straight sides and round corners. The 7.5 has a cover with two straight sides (top and bottom) and two rounded sides (left and right). Unless it's been swapped, that car should have the 7.5. Only 86+ V8 Mustangs got the 8.8.

the gears should work, but I still don't think that the shafts will, I have no data to back me up.... arent these also C-clips, Iono if 1/4" would be acceptable to accept the C-clip.....

You could do a Chyrsler 8.25, I know up here Cherokee guys just throw them away in favor of a D44....

I picked up my Explorer 8.8 from a wrecker for $100 canadian you pull, thats like 20 Bucks US :D

I've swapped turbo t-bird rears into mustangs and they are the same width. Ford used an 8.8 in the 86 svo mustang, 84 and 85 got the 7.5 rear.

Turbo t-birds had rear discs, and came with either 3.55 or 3.73 gears. You might also consider an aerostar rear. They are 8.8's with 5 lug axles, and are cheaper than dirt.

So I'm a retard?

Seems like you just proved my point..
Explorer Axle Shafts are Stagered Length. Mustangs have equal length... THe shafts won't swap and that is what I was saying.. Jackass

I've swapped turbo t-bird rears into mustangs and they are the same width. Ford used an 8.8 in the 86 svo mustang, 84 and 85 got the 7.5 rear.

I don't think so. Only V8s got the 8.8. While they had the same HP rating as the SVO, the V8 cars had a lot more torque. Here's an article about an '86 where the owner talks about swapping the 7.5 for an 8.8 out of a GT.

Three out of four Pirates I was referring to are retards. At least your post
was mostly right. You were right about the Sploder shafts not fitting the
housing, and the gears and carrier interchanging.

What I was referring to was that four of you retards said:

its a wider (WMS) axle than the 8.8 that came in the mustang.

WRONG!!! The axles are basically the same WMS if not the same.
Four of you jumping in saying its narrower implies it's significantly
narrower, just because it's a car axle.

And I am not a Jackass, I'm an Asshole. I've been
called "abrasive and confrontational" by my co-workers.
I can live with that, at least I'm right. :flipoff2:

Lol,

I stand corrected on the WMS part... :flipoff2:
